The idea is to rename them as luai_*, so they can be used by other Lua
macros (specifically luaL_argcheck and luaL_argexpected). C libraries
would use them only indirectly, through these macros. They would not be
part of the API and should not create source-API-incompatibilities (nor
ABI incompatibilities) with previous 5.4 releases.
Our only concern is that C extension libraries might end up using
__builtin_expect unknowingly. Would that be a problem?
